Application filed December 11, 1911. Serial No. 665,005.

To all whom 'it may concern:

Be it known that we, Altos L. KNIGHT and l/VILLIAM CLEMENTS, citizens of the United States, and residing at Philadelphia,

, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Type-Molds; and we do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming part of this specilication, and' to the figures and letters of reference marked thereon.

This invention relates to the manufacture of what are known as short body type, the latter possessing all the characteristics of ordinary printing type save as to the length of body, which latter is materially shortened, and the addition of means for effecting their retention in 'specially prepared forms or holders for application to addressing and similar'machines; and it has for its principal object the production of a mold, specially contrived and adapted `for use in commercial automatic type casting and composing machines, by means of which said type can be rapidly, accurately and economically produced, and, if desired, set up in justified lines ready for application to the forni or holder with which they are designed to be associated.

To these ends the invention consists in, the construction, combination and arrangement of parts constituting or forming elements of the type mold hereinafter fully described, the novel features whereof are specifically pointed out in theappended claims.

In the accompanying drawings, illustratinga preferred form of embodiment of said invention,-Figure 1 is a top plan view of the mold; Fig. 2,is a siniilar view with side blocks,v mold blade and mold plate omitted; Fig. 3 is a right hand end View; Fig. t is a vertical section in the plane of one side of the mold blade; Fig. 5 is a partial vertical section through the cross block near the end of nick pin; Fig. 6 is a perspective ot" the two side blocks detached; Fig. 7 is a perspective of the floor plate; Fig. 8 is a perspective of the moldplate; Fig. is a perspective of the two base sections of the cross block; Fig. 10 is aside elevation, and Fig. 11 an Vend View of the mold blade; Fig. 12 is a perspective of the jet ejector; Fig. 13 is' a perspective of the bottom niek pin; Fig. 14 is a perspective ofthe produced type.

The same numeralsdesignate like parts in the several figures. j' l i The type, Fig. 14, which the mold illustrated is designed tofproduce, comprises a head or character'l accurately formed in justified relation upon one end of the. short rectangular body 2, the opposite sides whereof, corresponding with the top and bottom of the character, contain retaining grooves or channels 3, while the base or foot is recessed part way across from one side, as at et, to furnish a means for determining the set of the character or its position in' the line when assembled, said one side bottom recess serving as a substitute for the 4usual indicating nick whose function in this respect is nullitied by the presence of the opposed retaining groove.

The mold is specially designed for use in automatic casting and composing machines of the type indicated in PatentNo. 625,998, dated May 30, 1899, and is provided with the usual base plate 5, front abutment 6 carrying adjust-able shoe 7, and squaring plate 8 adjustably attached to' base 5 parallel with front abutment G. In the angle between squat-ing plate 8 and base 5 and detachabl y secured to each of said members is a right angled or L-shaped floor plate 9, the upper faces 9 and 9" of the body and vertical members whereof lie lin parallel planes at right angles to the inner and outer faces 9" 9 of the vertical memberl )f said floor plate. ln the way or channohlletween squaring plate 8 and the angularfextension or vertical member of floor platei 9 are seated and secured two guide bloclts 10, 11 spaced apart by an' interposed point block 12 upon which they are clampedi by a through bolt 13. Bolts 8X passing through enlarged orifices in the squaring-plate 8 and opening; `next door plate 9 and a the-@movable jet ejector blade 81y the last named engaging` a earn plate 32 lined to plate sion ot vdoor plate 9. The Width of the extension 14 is somewhat in excess et that ot iace 9b and oyerhangs or projects beyond the inner vertical tace 9C While the proximate edges or glaces of said extensions 14 are in parallel planes perpendicular to tace 91 and et a thickness corresponding to the height of the body et the type to be produced.l ln theV example illustrated and tor the purpose oit producing side grooves 3 the opposing 'faces ot extensions 14 are each provided .with a rib or projection 15 preterably produced by slotting the tace longitudinally and inserting a filling1 piece 16, vthe latter projectingbeyond the tace ot ex? `tension 14 and heldr'in position by a tapered pin 17 er equivalent fastening device, in sorted 'from below so to be held from displacement by the contacting tace of the `door plate.

The sfjuaring plate 8 is notched or eut array7 as atI 1&5, opposite the channel. between guide bloclrs 10, 11 and is pro- Yvided uith an outside bearing 1l) for the onter end ot the mold blade carrier 20, the latter litted to slide between the proximate 'laces ot blocks 10, 11 and provided at its inner upper corner with the mold blade 21 filling` the space between the proximate, edges of extensions 14 and serving both as the Variable din'iensioning member for the mold cavity and a means tor ejecting the type therefrom; in other Words, the cross section ot the mold blade corresponds with the space or channel between extensions 14 and tace 9b, its sides being grooyed, as at E22, to tit ribs 15 and the under sur-,tace i( :rooved as at to iit thc nick pin Q4. rthis niet: pin. so called, is preferably inthe torni ot a cylinder inserted in a. hole drilled troni the tare 9C parallel with and partially intersecting :tace 9" ot the vertical member of the ,door plate the inner end ot' said pin terinirniitine; short ot the inner edges ot extensions li,'oyerhaiugiug the inner tare 9C, and haring the lower sertion ot the overhane'ing end cut away, as at in the plane t tace 9b.. 'lhe nii-l; pin 24 is retained. gainst longitudinal disj'ilaeement by a key l t3 located in a transi'erse zgroove 27 in iloor plate 9.

hi'ounted to reeiprorate longitudinally in the Way or rhannel between loor plate 9 and iront abutment t3 is the cross blnelr @il termine the removable side ol the mold cav ity and containing' the jet' or sprue openingp througrh which molten nletal is conducted to the bottoni oi; the mold rarity, the latter bounded on the sides by exteiuions14,1uold rllhe lower sections or limbs of base sections 30 are extended beneath tront abutnient 6 While the upper sections or stems project on theopposite side beneath eaten-- sions 14, and in the angle between the two limbs of the base sections is seated the squar ing plate 33 engaging shoe Y. Mold plate 29 and squaring plate 33 are each securely las tened to base sections 30 by bolts 34, 35, and by arranging` the squaring plate in the anguiar seat at the junction ot the two limbs "ons, the rigidity and initie of the base sect1 adjustment ot the associated elements ternir ing the cross bloeit is greatly promoted.

lt should be noted that when the cross block is in casting position, as indicated in Fig. 4, the top surfaces ot the mold platej mold blade and extensions ift' are in the same plane and torni a seat tor the reccp- 'tion ot' the matrix, ot which latter a large number are carried in the die-ease (not shown) for selective presentation to the mold; that the gate or passage in the crossbloclr is in register at' the top with the open ing or space around the over-hanging end. ot the niclr pin at the bottom et the incid cavity and at the bottom with the jet open-- ing 3G ot the nozzle seat in the base plate ti; and that at this period the jet ejector blade -l stands retracted or nithdrarm trom floor plate t), thereby openingthe gate tor around the nick piu into the` mold cavity. ritter the cast is made the ,cross-bloeit is moved to uncover the side ot the mold cavity and sever thel jet 'from the type, the ejector blade is advanced to discharge the jet'n and a type carrier, (not shown) presented to receive the type as discharged 'from the mold by the mold blade, alter which the type carrier and eross-bloclt arr-l shitted again7 the one to trans-ter the contained type to the assembling` devices or dcliver it to a suitable reeeptarhe` and the other to closev the side ot the mold pref inunary to the adjustuient fior set and the applirition et for charaeteiz rthe mold blade carrier ree@ reception ot the point bloeit down upon its seat-on the. than: bearing;l l5) by a top guide ill' detain cured to bloeit` t() and ena'afi edge ot said carrier.

Corresponding ends of passages 39, 40 are united through a branch 4l and the opposite end-of each is connected by a branch 42 or 43 with a port 44 or 44X adapted to register with a similar port in the base plate for the admissionand discharge of a cooling agent, such as water.

Owin to its motion and concealed position di culty has been experienced in insuring and maintaining proper .lubrication of the jet ejector inthe'cross-bloek, andv to overcome this the following construction has been devised. `The proximate faces of the two 'base sections in contact with the jet ejector are each furnished with a groove 45, preferably diagonally disposed relatively to the line of motion of the ejector blade and extending transversely thereof, and one of said sections is provided with an oil recepta'cle 46 communicating through a passage 47 with a groove or duct 48 located to one side of groove 45. The ejector blade is turnished with a notch or opening 49 adapted to register alternately with duet' 48 and grooves 45. The arrangement is such that when the ejector blade is in its retracted position, to permit the cast to be made, opening 49 will register with duet 48 and receive a supply of oil therefrom, and when the Vblade is reciprocated, to eject the jet, opening 49 will be brought into register with grooves 45 so as to permit the contained supply to flow into said grooves.

The mold as a whole is designed and adapted for use in the type cast-ing machines hereinbefore referred to as a substitute for the full body mold previously employed, but when employed for setting up composed matter the type assembling devices should be modied to correspond with the reduced dimensions of the produced type bodies.
